Typical Application Circuit
General Description
The AW37501 is designed to support positive /negative supply for driving TFT-LCD panels mainly in smartphones and tablets. The device employs a single inductor scheme to provide a small bill-ofmaterial and smallest PCB solution size.
It integrates a step-up DC-DC converter for preceding supply. An architecture with LDO and negative charge pump (NCP) generates dual outputs at +5.4V (default) and -5.4V (default), whose voltages can be programmed via an I2C patible interface.
The device offers excellent line and load regulation performances, as well as load transient. It Features an outstanding efficiency that is greater than 80% when IOUT>10m A and 85% when IOUT>40m A. With its input voltage range of 2.7V to 5.5V, it can be powered by single-cell batteries (Li-Ion, Ni-Li, Li Polymer).
